English(EN) Phase-HDC: Replacing Optimizer History with Gradient Thresholds in Discrete Phase Learning

新的Phase-HDC方法大幅降低AI模型训练内存需求

作者 PulseAugur 编辑部 · [1 个来源] · 2026-10-09 04:00

研究人员开发了一种名为Phase-HDC的新训练方法，该方法显著降低了训练紧凑模型（尤其是高维分类器）的内存需求。该方法用简单的梯度阈值替换了优化器过去梯度的历史记录，仅当梯度足够大时才更新参数。Phase-HDC在内存使用量大大减少的情况下，实现了与具有6位矩的Adam相当的准确性，存储量比标准的float32 Adam少23倍。虽然与float32 Adam相比准确性略有下降，但Phase-HDC在多个数据集上优于8位Adam，尤其是在8位Adam失败的字节级文本预测方面。 AI

影响该方法有望在内存有限的硬件上训练更复杂的模型，从而可能使先进的AI功能更加普及。

Phase-HDC：在离散相位学习中使用梯度阈值替换优化器历史记录

arXiv:2610.10630v1 Announce Type: cross Abstract: Training a compact model often needs far more memory than storing it, because the optimizer keeps its own records of past gradients. For a hyperdimensional classifier whose learned parameters are low-bit angles, which we call a \e…
